Questions

Is there a KiCad symbol and footprint for the CH571F?

Yes. The symbol is EasyEDA_Cloud:CH571F and the footprint EasyEDA_Cloud:QFN-28_L4.0-W4.0-P0.40-BL-EP2.7, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH571F?

QFN-28-EP(4x4), with 29 pins. Its footprint is drawn on this page.

Where is the CH571F datasheet?

WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.

Where can I order the CH571F?

JLCPCB lists it as part C2856288, with 2,115 in stock; the sellers' links on this page open their listings.

What can replace the CH571F?

Parts like it in the library: the PIC18F25Q43-I/STX by Microchip Technology, the PIC18LF26K40-I/MV by Microchip Technology, the PIC16F18854-I/MV by Microchip Technology and the ESP8685H4 by Espressif Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CH571F?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
